SPECIFICATION forming part of Letters Patent No. '711,81 1, datedOctober 21,1902.

Application led April 2l, 1902. Serial No. 104,024. (No model.)

T0 AZZ whom, it' nfl/ay concern:

Be it known that I, ALFREDO ALONZO-CON- SOLI, a subject of the King ofItaly, residing at Catania, Italy, have invented a new and usefulImprovement in Retorts for Subliming and Refining Sulfur; and I dohereby declare the following to be a full, clear, and exact descriptionof the same.

This invention has for its object a new design of retort for refiningand subliming sulfur which has on all the other retorts heretoforegenerally used the advantage of allowing a continuous work with aconsiderable economy of time and fuel.

The invention is illustrated by the accompanying drawings, and in orderto better explain the modiications and the improvements of the newsystem as compared with the older method, Figure l shows a top view ofthe retort. Fig. 2 is a section taken on the line 0c of Fig. l, and Fig.3 is a section taken on the line y y of Fig. l.

In all the several views like parts are designated by the same lettersof reference.

According to the system used up to the present the smelting vessel isplaced above the retort, with which it communicates by means of a valvedtube. The smelting vessel is charged with raw sulfur in pieces, andafter this has been melted by the heat developed in the furnace thevalve is opened and through it the molten sulfur ows in the secondretort.

The rapid introduction into the retort of aV large mass of liquid sulfurthe temperature of which is considerably inferior to that of the retortproduces a cooling of the latter, and itrequiresa long time, nearlythreehours heating in the ordinary cases,to bring it again to its previoustemperature. The sublimation of the whole quantity of sulfur containedin a retort of ordinary size requires about six hours, so that of aworking day of twentyfour hours only sixteen hours of actual labor maybe utilized, while during eight hours the retort remains inactive,causing a considerable waste of fuel. The new retort avoids all theseinconveniences.

ofa bent tube c.

As will be seen in the drawings, the smelting vessel a is placed side byside with va retort b, with which it communicatesby means The vessel ais charged with raw sulfur in pieces, which after melting passes throughthe tube c into the retort a as soon as it reaches the level f. It istherefore sufficient to keep the melted sulfur at the level g g in thevessel d for maintaining the liquid at the same level in the retort b,wherein the melted sulfur coming from c substitutes continuously thevaporized sulfur. In order to obtain a continuous and uninterruptedfeeding, it is only necessary that the raw sulfur be supplied to thevessel c as the melted sulfur descends, so as to avoid its loweringbelow ff.

It is nearly superduous to remark that the smelting vessel as well asthe retort may be of any form and that their position may also bedifferent. The characteristic features of the invention consist in thedisposition of two vessels in communication, so as to keep constantly inthe one the same level as in the other.

I claim- 1. In a retort for reining and subliming sulfur, thecombination with a melting vessel, of a sublimation-retort upon the samehorizontal plane therewith, and a communicating tube, the extremity ofwhich within the melting vessel is below the level of the liquidtherein, substantially as described.

` 2. In aretort for subliming and refining sulfur, theombination with amelting vessel a, of a sublimation-retort b upon the same horizontalplane therewith, and a communicating tube c, the extremity of whichwithin the melting vessel is bent and below the level of the liquidtherein, substantially as described.

In testimony'whereof I have signed this speciication in the presence oftwo subscribing witnesses.
